Chip card with at least one application

Abstract

The invention relates to a chip card with at least one application for which an implementation ( 4 ) and an entry ( 5 ) referring to the implementation ( 4 ) are present on the chip card ( 1 ). The inventive chip card is characterized in that a plurality of entries ( 5 ) referring to the same implementation ( 4 ) are present.

The invention claimed is: 
     
       1. A chip card comprising at least one application for which an implementation and an entry referring to the implementation are present on the chip card, and wherein a plurality of entries referring to the same implementation are present on the chip card, wherein the implementation has a plurality of applications associated therewith, with a separate entry being present for each application and in that the implementation is executed in different ways depending on which entry the implementation starts with. 
     
     
       2. The chip card according to  claim 1 , wherein the entries referring to the same implementation characterize different virtual applications. 
     
     
       3. The chip card according to  claim 1 , wherein the entries each contain a freely selectable information sequence. 
     
     
       4. The chip card according to  claim 3 , wherein the freely selectable information sequences of those entries referring to the same implementation each have a different content. 
     
     
       5. The chip card according to  claim 3 , wherein the freely selectable information sequences have specifications for execution of the associated implementation. 
     
     
       6. The chip card according  claim 1 , wherein the chip card is intended for use in a handset of a mobile phone system. 
     
     
       7. The chip card according to  claim 6 , wherein a single implementation is present for a plurality of virtual applications for proving a network access authorization. 
     
     
       8. The chip card according to  claim 7 , wherein an entry is present for each virtual application for proving a network access authorization, the entries referring to the same implementation and wherein a different network access authorization is made available through each entry. 
     
     
       9. The chip card according to  claim 8 , wherein the entries have different parameters that are evaluated when invoking the virtual applications for proving a network access authorization and effectuate the use of the data belonging to the particular network access authorization. 
     
     
       10. A method for executing an application available on a chip card, comprising the steps:
 evaluating one of a plurality of entries present on the chip card and referring jointly to a same implementation of the application on the chip card, the implementation having a plurality of applications associated therewith with a separate entry present for each application, and 
 executing said implementation in different ways depending on which entry the implementation starts with. 
 
     
     
       11. The method according to  claim 10 , wherein the implementation present on the chip card is executed in different ways depending on which of the entries referring to the implementation is evaluated.
